The isolating terminals of Series 8082 can be used to manually isolate circuits for maintenance and test purposes. The isolating terminals are mounted in Ex e enclosures and may be operated in energized condition even in explosion-protected areas. When the contact is open, the incoming line terminal is covered. The actuator can be padlocked in zero position according to IEC/EN 60947-5-1 with a padlock. The devices can be combined into blocks using special top hat rails, which can be found in the accessories.
